Technical Field

[0001] This utility model belongs to the field of valve manufacturing technology, and specifically relates to an overpressure protection mechanism for a temperature control head. Background Technology

[0002] In temperature control equipment, the overpressure protection mechanism of the temperature controller is a key component to ensure the safe and stable operation of the equipment. However, traditional overpressure protection mechanisms of temperature controllers have many shortcomings in practical applications.

[0003] Traditional temperature controller overpressure protection mechanisms are not precise or flexible enough in adjusting the overpressure seat movement distance. Accurate control of the overpressure seat movement distance is crucial for achieving precise temperature sensing and protection functions. Traditional mechanisms cannot precisely adjust the downward movement distance and position of the overpressure seat according to actual needs, resulting in low temperature sensing accuracy and the inability to adjust the sensing protection temperature, thus reducing the flexibility of the temperature controller overpressure protection mechanism. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a highly flexible overpressure protection mechanism for a temperature control head that can adjust the sensing protection temperature.

[0005] The objective of this utility model can be achieved through the following technical solution: a temperature control head overpressure protection mechanism, including a temperature control base, an overpressure base provided in the inner cavity of the temperature control base, a spring provided in the inner cavity of the overpressure base, an overpressure rod provided on the top of the spring, a liquid temperature sensing element sleeved on the top of the overpressure rod, a housing sleeved on the top of the liquid temperature sensing element, an indicator ring sleeved on the bottom of the temperature control base, a threaded connection between the surface of the temperature control base and the inner wall of the housing, a scale line provided on the surface of the housing, and a pointer fixedly connected to the surface of the indicator ring.

[0006] In the above-mentioned overpressure protection mechanism for a temperature control head, a connecting nut is fitted at the bottom of the temperature control base, an external thread is provided on the surface of the temperature control base, and an internal thread is provided on the inner wall of the outer shell.

[0007] In the above-mentioned temperature control head overpressure protection mechanism, a central rod is integrally formed at the center of the overpressure base, and the top of the central rod extends into the inner cavity of the overpressure rod.

[0008] In the above-mentioned overpressure protection mechanism for a temperature control head, an elastic sheet is sleeved on the surface of the overpressure rod, and the elastic sheet is located in the inner cavity of the liquid temperature sensing element.

[0009] In the above-mentioned overpressure protection mechanism for a temperature controller, a reinforcing mechanism is installed at the bottom of the indicator ring. The reinforcing mechanism includes a connecting plate, the bottom of which contacts a vertical plate. A first threaded rod is connected through the surface of the vertical plate, and a clamping ring is movably connected to one side of the two first threaded rods facing each other.

[0010] In the above-mentioned overpressure protection mechanism for a temperature control head, a first guide rod is connected through the surface of the vertical plate, one end of the first guide rod passes through the vertical plate and is fixedly connected to a clamping ring, and an anti-slip pad is adhered to the inner wall of the clamping ring.

[0012] Compared with existing technologies, the advantages of this temperature control head overpressure protection mechanism are: precise adjustment of the position of the overpressure base, determination of the adjustment distance of the overpressure base by observing the position of the pointer and the scale line, and the upward movement of the overpressure base after the liquid temperature sensing element detects high temperature, thus separating it from the electrical components and realizing the overpressure protection function.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the overpressure protection mechanism of this temperature control head includes a temperature control base 1, an overpressure base 2 is provided in the inner cavity of the temperature control base 1, a spring 3 is provided in the inner cavity of the overpressure base 2, an overpressure rod 4 is provided on the top of the spring 3, a liquid temperature sensing element 5 is sleeved on the top of the overpressure rod 4, a housing 6 is sleeved on the top of the liquid temperature sensing element 5, and an indicator ring 7 is sleeved on the bottom of the temperature control base 1. The surface of the temperature control base 1 is threadedly connected to the inner wall of the housing 6, a scale line 8 is provided on the surface of the housing 6, and a pointer 9 is fixedly connected to the surface of the indicator ring 7, which enables the overpressure base 2 to move vertically and precisely adjust the position of the overpressure base 2. The adjustment distance of the overpressure base 2 is determined by observing the position of the pointer 9 and the scale line 8. When the liquid temperature sensing element 5 detects a high temperature, it causes the overpressure base 2 to move upward and separate from the electrical components, thereby realizing the overpressure protection function.

[0020] A connecting nut 11 is fitted on the bottom of the temperature control base 1. The surface of the temperature control base 1 is provided with external threads, and the inner wall of the outer shell 6 is provided with internal threads. By setting the connecting nut 11, it is convenient for the temperature control head overpressure protection mechanism to be quickly and securely connected with other equipment, which improves the installation efficiency. Through the threaded connection, the temperature control base 1 and the outer shell 6 are tightly connected, ensuring the overall stability of the mechanism.

[0021] A central rod 10 is integrally formed at the center of the overpressure base 2. The top of the central rod 10 extends into the inner cavity of the overpressure rod 4. When the overpressure rod 4 moves up and down under the action of the liquid temperature sensing element 5, the central rod 10 ensures that the overpressure rod 4 can only move in a straight line, avoiding deviation and shaking, and improving the stability and accuracy of the movement of the overpressure rod 4.

[0022] An elastic sheet 12 is fitted on the surface of the overpressure rod 4. The elastic sheet 12 is located in the inner cavity of the liquid temperature sensing element 5. When the temperature of the liquid temperature sensing element 5 rises, the elastic sheet 12 is heated and elongated, causing the overpressure rod 4 to move upward, which in turn causes the overpressure base 2 to move upward, thereby realizing the separation of the overpressure base 2 from the electrical components.

[0023] In use, the device is connected to the connecting nut 11. The outer shell 6 is rotated and threadedly connected to the temperature control base 1. The outer shell 6 moves downward, causing the liquid temperature sensing element 5 to move downward. The liquid temperature sensing element 5 causes the overpressure rod 4 and the overpressure base 2 to move downward. The bottom of the overpressure base 2 contacts the electrical components. The adjustment distance of the overpressure base 2 is determined by observing the position of the pointer 9 and the scale line 8. When the device temperature is higher than the preset value, heat is transferred to the overpressure base 2, the overpressure rod 4 and the elastic plate 12. The elastic plate 12 expands due to heat, causing the overpressure rod 4 and the overpressure base 2 to move upward. The overpressure base 2 separates from the electrical components, thus achieving overpressure protection. Example

[0024] like Figure 2 and Figure 4 As shown, the structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference is that a reinforcing mechanism 13 is installed at the bottom of the indicator ring 7. The reinforcing mechanism 13 includes a connecting plate 130. The bottom of the connecting plate 130 contacts a vertical plate 131. A first threaded rod 132 is connected through the surface of the vertical plate 131. A clamping ring 133 is movably connected to one side of the two first threaded rods 132. Through the cooperation of the connecting plate 130, the vertical plate 131, the first threaded rods 132 and the clamping ring 133, the entire temperature control head overpressure protection mechanism can be firmly fixed in the installation position, so that the two clamping rings 133 are close to each other and clamp the object at the installation position, effectively preventing the mechanism from vibrating during use and ensuring the stability and reliability of the mechanism's operation.

[0025] A first guide rod 134 is connected through the surface of the vertical plate 131. One end of the first guide rod 134 passes through the vertical plate 131 and is fixedly connected to the clamping ring 133. An anti-slip pad is adhered to the inner wall of the clamping ring 133. When the position of the clamping ring 133 is adjusted by the first threaded rod 132, the first guide rod 134 provides precise guidance for the movement of the clamping ring 133, ensuring that the clamping ring 133 can only move in a straight line. The anti-slip pad increases the friction between the clamping ring 133 and the clamped object, further improving the clamping firmness and preventing slippage during the operation of the mechanism.

[0026] A second threaded rod 135 is connected through the top of the connecting plate 130. The bottom of the second threaded rod 135 passes through the inner cavity of the vertical plate 131 and is threadedly connected to the vertical plate 131. A second guide rod 136 is fixedly connected to the bottom of the connecting plate 130. The bottom of the second guide rod 136 passes through the inner cavity of the vertical plate 131 and is movably connected to the vertical plate 131. Rotating the second threaded rod 135 can change the distance between the connecting plate 130 and the vertical plate 131 and adjust the clamping position of the clamping ring 133 to adapt to different installation positions and requirements. The second guide rod 136 ensures the stability of the connecting plate 130 during movement, making the adjustment process smoother and more accurate.

[0027] In use, rotating the second threaded rod 135 causes the vertical plate 131 to move downwards. The vertical plate 131 then causes the first threaded rod 132 and the clamping ring 133 to move vertically. Adjusting the height of the clamping ring 133, rotating the first threaded rod 132 to connect it to the vertical plate 131, causes the first threaded rod 132 to move the clamping ring 133. The clamping ring 133 holds the testing equipment and reinforces the overpressure protection mechanism of the temperature control head.
